Claims

[Scope of utility model registration request]

A connecting shaft is provided that connects the front wheel drive system and rear wheel drive system of the vehicle to transmit driving force from the engine, and a dog clutch installed on the connecting shaft connects the front wheel drive system and the rear wheel drive system. A clutch adjustment mechanism that stops transmission of driving force from the dog clutch when the difference in driving force from the wheel side drive system exceeds a predetermined value, and a control means that controls the clutch adjustment mechanism to change the predetermined value. A power transmission device for a vehicle, characterized in that:
